MACHINE FOR FORMING ORNAMENTS AND CUTTING THEIR SHANKS.

SPECIFICATION forming part of Letters Patent No. 500,480, dated June 27,1893.

Application filed August 4, 1892. Serial No. 442,154. (No model.) I

To all whom it may concern.-

Be it known that I, LoUIs A. EUCKER, of Hoboken, in the county of Hudsonand State of New Jersey, have invented a new and Improved Machine forForming Ornaments and Cutting their Shanks, of which the following isafull, clear, and exact description.

My invention relates to an improvement in devices for forming ornamentsand cutting their shanks to suitable length, and the principal featureof the invention is to provide a machine which will be exceedinglysimple, durable and economic in its construction and by the use of whichcleaner and quicker work can be produced than by the old style ofmachine, as the fire is located nearer to the molds or dies and themolds are located well above the table of the machine and at one sidethereof, thus enabling the operator at all times to conveniently notethe progress of the work; and a further object of the invention is toprovide a means whereby as the ornament is formed the shank thereof willbe automatically cut to a suitable length.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth and pointed out inthe claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a side elevation of the machine. Fig. 2 is a centralvertical longitudinal section through the body of the machine, thesection being taken practically on the line 22 of Fig. 3. Fig. 3 is aplan view of the body of the machine. Fig. 4 is a transverse verticalsection taken practically on the line 44 of Fig. 2. Fig. 5 is a detailperspective view of the knife. Fig. 6 is a detail view of the clam pingjaws for the shank of the ornament, the view being taken on the line 66of Fig. 3; and Fig. 7 is a perspective view of an ornament and itsshank.

The main body of the frame of the machine consists of a block 10, whichis preferably made quite thick at its central portion and reduced at itsends, the end portions being apertured to receive screws or otherfastenand the block has formed integral with its outer face, or attachedthereto, a transverse breast plate 12. The outer end of the body blockis provided with a slide-way 13, vertically arranged, the said slide-waybeing preferably somewhat dove-tail shape in cross section. In thisslide-way a trip plate B, has vertical movement. The lower end of thetrip plate is made solid, the solid portion being indicated at 14 inFig. 2, but the upper portion thereof comprises two members 15 and 16,and these members are located one at each side, engaging with the sidewalls of the slide way. Each member 15 and 16 extends transverselybeyond the slide-way in the body block, and the under faces of theextensions 15 and 16 of the trip plate are downwardly beveled, asindicated at a in Figs. 1 and 2,

and these beveled faces of the trip plate are adapted to engage with theupper beveled surface of a cross bar 17, which cross bar is locatedimmediately in front of the slide-way; and through said cross bar, atits center, the threaded end of a shaft 18, is passed. The shaft 18 isheld to slide in a suitable bearing in the body block, and it occupiesan inclined position, slanting from the breast plate downward indirection of the table, as best shown in Fig. 2. The cross bar isprovided with a threaded opening through which the threaded end of theshaft passes.

The breast plate, 12 has an upward inclination in direction of the endcarrying the trip plate, as is shown in Fig. 1; and upon the outer endof the shaft 18, which extends some distance beyond the breast plate adie-plate 19, is secured to it, the attachment being made at or near thecenter of the plate. That portion of the shaft passing through the dieplate is threaded, as is likewise the wall of the aperture receiving thethreaded portion of the shaft, and a lock nut 20, is screwed upon theouter end of the shaft to a bearing against the outer surface of thedie-plate. A spring 21, is coiled around the shaft 18 between the breastplate and the die plate, having an engagement with each, so that whenthe shaft is carried endwise downward to draw the die-plate in directionof the breast plate the spring 21, is compressed, and when tension isremoved from the shaft 18 the spring 21 restores the shaft to its normalposition.

The die plate 19 is guided in its movement to and from the breast plateby means of guide rods 22, located one near each end of the die plateand passing loosely through it. The inner ends of the guide rods aresecured to blocks 23, and these blocks are adj ustably attached to theouter face of the breast plate near the lower end thereof, suitablechannels being provided in that side of the face of the plate for theirreception. The channels are preferably made somewhat dove-tail shape incross section, but may be otherwise formed, and the blocks are securedto place by means of set screws or their equivalents.

At the upper central portion of the dieplate one section of a die islocated, preferably the female section 24, and this section of the dieengages with the inner face of the die-plate, extending essentially at aright angle therefrom. The die section 24, is removably attached to theplate, being screwed thereon and the screw shank being provided with alock nut or washer. By this means the section 24 of the die maybeexpeditiously and conveniently removed if in practice it is founddesirable.

each side of this opening. channels two slides are securely fastened,which slides are designated in the drawings as 26 and 27. These slidesare permanently held in connection with the breast plate by means of anadjusting screw 28, or the equivalent thereof. The slides at their innerends project over or into the opening 25 in the} breast plate, and theslide 26, which is opposite the die-plate 19, carries at its inner endthe male section 29 of the die, that is, this slide-26 carries one-halfthe male section of the die, and the inner end of the plate back of thedie section is inclined and channeled, E as illustrated at d in Fig. 2,the inclination being shown to much greater advantage in Fig. 3.

shown in Fig. 6.

In the channel-way of the breast plate at the opposite of the breastplate opening 25 a die-carrying plate and a locking plate are located,bearing the same relation to each other and being directly opposite thedie and looking plates 26 and 27 stationarily attached to the breastplate. The slide-die-carrying plate and locking plate are designatedrespectively as 32 and 33, and the inner end of the plate 32 carries asection 34 of the male die, corresponding to the section 29 upon thestationary plate; and when the two sections of the die are broughttogether and the complete male die is formed it is capable at that timeof readily entering the female section of the die.

The locking plate 33, is provided with a rabbet upon its side facing thedie plate 19, and the rabbeted portions of the two locking plates 27 and33 are such that when these two portions of the plates are slid one overthe other, a cross section taken at that point will show the samethickness as that of the body portion of either plate. The rabbetedportion of the sliding locking plate 33, however, as shown in Fig. 6, isprovided with a longitudinal slot 35, the lower wall of which slot isabout upon a level with the upper edge of the lip 31 of the oppositesliding plate.

The sliding, locking and die-carrying plates are guided in theirmovements in their slideway by means of a strap-like plate 36, which issecured to the outer surface of the breast plate; the outer side face ofthe strap-like guide 36, is provided with a recess, and through thisrecess the cam surface 37 of a cam bar 38, is passed, the cam surface ofthe bar being constantly in engagement with the outer ends of thelocking and die-carrying plates 32 and 33. After passing the recess inthe guide strap 36, the cam bar 38, passes through an opening 39,produced in the breast plate, as shown in Fig. 4. The outer end of thecam bar 38, is securely fastened to the die 19 at one side thereof. Aspring 40, secured to the outer face of the breast plate engages withthe sliding die-carrying plate 32, as shown in Fig. 4, and the tendencyof this spring is to force said die-carrying plate away from the opening25; and a connection is made between the plate 32 and the locking plate33, whereby when the former plate is carried on tward by the spring 40the latter plate is also carried in the same direction.

In a longitudinal recess in the top of the body block 10, aknife-carrying plate 41, is pivoted. This knife-carrying plate extendsforwardly through an opening 25,'as shown in Figs. 2 and 4, somedistance below the die- I carrying plates 26 and 32; and the oppositeThe slide 27, which is back of the die-carj ryi'ng slide 26, is providedat its inner endj upon its rear face with a rabbet 30, as shown best inFig. 6, and the rabbeted portion of the i slide 27, which may be termeda locking plate, is recessed, forming thereby a lip 31, likewise end ofthe knife-carrying plate extends over the slide-way in the rear end ofthe body block 10, between the members of the trip plate B. To the rearend of the knife-carrying plate a link 42 is secured, and a cross bar43, connecting the arms of the trip plate passes through the link, as isbest illustrated in Fig. 2.

The knifeD is shown in detail in Fig. 5, and the knife comprisespreferably two L-shaped or angular sides 44 and a cutting surface 45connecting the said sides, the back of the en tting surfaces of theknife being straight and the front portion more or less inclined. The

cutting portion of the knife is adapted to enter into the opening 25 inthe breast plate,

surfaces of the male die sections.

and it is also adapted to have sliding movement upon the rear faces ofboth of the looking plates 27 and 33, the side sections 44 of the knifehaving free movement between studs 46 and the back face of the breastplate, the studs being made to extend upward from the body block 10. Theknife is raised when the forward end of its carrying plate or lever 41,is elevated. The knife is not positively secured to the lever, but isconnected thereto ordinarily by a link 47, connected with the centrallower portion of its cutting surface, which link is carried downwardthrough an opening 48 in the lever, as shown in Fig. 2, and then outwardbeyond the breast plate.

Two springs 49, are located one at each side of the table in front ofthe rear end of the body block, and these springs are adapted to assistthe trip plate 14 in its upward or return movement, the springs beingengaged by studs 50, projected from the outward members of the studs ofthat plate.

The machine is designed primarily to mold ornaments from glass or fromother substance either pliable when cold or when heated, and to secureto the ornaments at the time that they are formed a shank of wire or anyother approved material, and simultaneously with the formation of theornament and its fixture upon its shank to cut the shank to apredetermined or desired length. This is accomplished in the followingmanner: One end of a length of wire, a section of which is shown in Fig.7 and is designated as E, is dipped in molten glass, or other materialfrom which the ornament is to be formed, and while the material is stillhot the wire is passed into the opening 25 in the breast plate andbetween the locking plates in such a manner as to bring the heatedmaterial against the outer While this is being done the trip plate 14,is drawn downward by means of a treadle 51, or other power, and upon thedownward movement of the trip plate it forces the shaft 18 rearward,bringing the die plate 19 in direction of the breast plate; and as thesetwo plates approach the cam bar 38 is made to act upon the movablelocking plate and the movable plate carrying the male die section in amanner to force these plates in direction of and in contact with theopposing and equivalent fixed plates. By this means the locking platessliding one upon the other clamp the shank or the wire, as the wireenters the slot 35 of the locking plate 33, and the solid portion ofthis plate is carried over the lip of the opposing locking plate 27.Just at this time the male and female sections of the die will bebrought together and the ornament formed, as shown at E in Fig. 7,andjust as the formation of the ornament is about completed the trip block14 will have descended a sufficient distance to cause its cross bar 43to bear down upon the link 42, thus raising the forward end of the lever41, which carries the knife D upward and severs the wire, the wireattached to the ornament constituting its shank. In order that the tripplate 14 may work up and down without interruption an opening 52, isproduced in the table through which it passes.
